CULTIVATOR ATTACHMENT.

Specification of Letters Patent.

Patented July 23, 1912.

Serial No. 646,633.

To all "whom it may concern:

Be it known that I, ERNEST J. HOETZEL, a citizen of the United States, residing at Burlington, in the county of Milam and State of Texas, have invented new and useful Improvements in Cultivator Attachments, of which the following is a specification.

This invention relates to cultivator attachments, and it has for its object to provide an adjustable yoke or arch of simple and improved construction whereby the distance between the cultivator beams may be quickly and conveniently adjusted and regulated, and whereby the proper distance between said beams maybe preserved when the cultivator is in operation.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claim.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise. structural details therein exhibited, but that changes, alterations and modifications within the scope of the claim may be resorted to when desired. V

In the drawings,-Figure 1 is a side elevation of a device constructed in accordance with the invention. Fig. 2 is a front elevation, the cultivator beams being shown in section and dotted lines being employed to indicate a different adjustment of said beams. Fig. 3 is a sectional detail view taken on the line 3-3 in Fig. 2. Fig. 1 is a sectional detail view taken on the line 4t in Fig. 1. Fig. 5 is a sectional detail view taken on the line 5-5 in Fig. 2.

Corresponding parts in the several figures are denoted by like characters of reference.

The head or supporting member of the improved device consists of an approximately V-shaped casting A having limbs or side members 1 and 2. The limb or side member 1 is of arcuate form, and its convex edge is toothed to form a rack 3 which is concentric with an aperture 4 near the upper end of the limb or side member 2. The latter side member terminates at its upper extremity in a fork formed by a transverse recess or notch 5 in which a pair of legs or adjusting members 6, 6 are pivoted upon a pin or bolt 7. A pin orbolt 8 extending through theaperture 4t affords a fulcrum for a lever 9 having a slot 10 through which the rack member 3 is guided, said rack being engaged by a spring actuated stop member 11, whereby the lever may be retained in adjusted position with reference to the rack, which latter constitutes a part of the sup porting member or head A. Mounted pivotally upon the lever 9 is a handle 12 which is connected by a link 13 with the stop member 11, which latter may thus be retracted against the tension of its actuating spring 14 to disengage said stop member from the rack 3 for the purpose of enabling the lever to be adjusted.

The adjusting members or legs 6, 6 are connected together by means of a cross bar or slide 15 having slots 16 for the passage of the legs. Said slide is provided upon the rear side thereof with lugs or brackets 17 which are connected by means of links 18 with the lever 9, said links being connected with the lever by means of a bolt 19 which straddles the slot 10 adjacent to the concave edge of the link or side member 1 which is thus reinforced and braced. The toothed edge of the limb 1 rides upon a cross piece 20 in the slot 10 which also constitutes one of the supporting members for the spring actuated stop 11.

In the operation of this invention, the lower ends of the legs or adjusting members 6, 6 are connected with the cultivator beams in any convenient and appropriate manner, said legs occupying normally a substantially upright position, while the lever 9 extends rearwardly within reach of the operator who, by manipulating said lever, may move the slide 15 upward or downward upon the legs 6, thereby spreading said legs apart or drawing them together, as may be required, in order to effect the desired adjustment of the cultivator beams. The latter will be retained at the desired adjustment by the stop member 11 engaging the rack bar 3, thereby retaining the lever 9 and the leg adjusting slide in a stationary position.

The improved adjusting device, as will be seen, is simple in construction, and it may be readily applied to any riding cultivator of conventional construction for the purpose of enabling spacing of the cultivator beams to be easily and quickly effected.

Having thus described the invention, what is claimed as new, is

In a device of the character described, a V-shaped head member, one limb of which is provided at its upper extremity with a transverse notch forming a fork and with an aperture below said notch, and the other limb of the head member constituting an arcuate rack concentric with the aperture in the first limb, a pivot member engaging the aperture, a lever fulcrumed upon the pivot member and having a slot'for the passage of the arcuate rack, a spring actuated stop member associated with the lever and engaging the arcuate rack, legs supported pivotally in the transverse notch at the upper end of that limb of the head member which carries the lever, a slide having slots for the passage of the legs, the slide being thereby guided upon the legs to space the latter apart, said slide having rearwardly extending brackets, and links connecting said brackets with the lever.

In testimony whereof I afliX my signature in presence of two witnesses.
